distort Ri colorbar

deform Ri by Ri/(|Ri|+.25) so that
+infinity maps to +1
1/4 (the critical Ri #) maps to +0.5
0 maps to 0
-1/4 maps to -0.5
-inftinity mapts to -1
Calculate the corrected Stokes drift

using calculated <u'w'> and <v'w'>
and the estimated stokes drift calculate the corrected
version of the stokes drift

Stokes Drift production =
[ <w'u'>*cos(theta) + <w'v'>*sin(theta) ]*S_0*2*k*exp(2*k*z)
adjust where plotting defaults get stored, this may change again

Also start splitting into tke + gen/diss and tke + flux plots
more mucking about with overarching plots
start a command to merege dag files w/o overlap
